Specification of Letters Patent.

Application filed October 2, 1906. Serial H0- 337,116.

To'all whom it may concern:

Be it known that I, HENRIK V. Loss, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Machines for Rolling Tires, of which the following is a specification...

My invention relates to improvements in machine's for rolling wheel tires, and more particularly tires for locomotive or railwaycar wheels, and the objects of my invention are to furnish a machine of this character all the rolls of which will be so disposed as to roll the metal at all points equally, that is to say, without dragging or drawing certain parts of the metal in lines not concentric with the center of the tire; to furnish a machine of this character, the guide'or truing up rolls of which will act automatically, and to embody such details as will compensate for the wear of the rolls, thus enabling the operator at all times, by mere adjustment, to maintain the trilecircular shape of the tire. 4

In the present case the standard hydraulic cylinders for operating the guide or truing up the rolls have been replaced by a central electric motor which working through its proper connections, screws, levers, &c. furnishes a more positive and exact movement to the rolls in question. A

In the traveling carriage the lower driven edging roll has been made a cone oi similar dimensions to the up per one, this detail is believed to be new and its value is apparent. These coned rolls are so proportioned that the point of intersection of the center line of each roll with its corresponding elongated face line coincides with the center of a five foot tire, this dimension (five feet) being settled upon because of representing from 90% to 95% of the total number of tires (locomotive and ear wheels) owned and operated by one of the largest trunli lines in the United States, but of course this dimension can be changed without in any way altering my invention. The standard construction of these edging rolls is either two parallel cylindrical rolls, or

one cylindrical bottom roll operating in conjunction with a conical top roll. The purpose of these rolls is to reduce the width of the tire down to its finished dimen sions; and the purpose of the automatic arrangement of the guide rolls is two fold, first to produce a tire so true that little or no turning is necessary; second, to minimumize labor by saving one or more operators, as well as doing away with his or their personal errors.

In the accompanying drawings forming part of this specification, and in which similar figures of reference indicate similar parts throughout the several views: Figure 1, a plan of my improved tire rolling mill; Fig. 2, an enlarged section on line 22, Fig. 1, showing the flanged edging rolls and the means for carrying them;

To use the machine a slab is properly forged and punched after which it isinserted in the machine in a horizontal position. This blank has a diameter very much'emaller than the finished tire while the cross section of metal is correspondingly greater.

In Fig. 1, which is a plan of'my nachine, 39 represents a tire in place between the rolls which are as follows: 40, Figs. 1, l719-2425, is a driven ver-- tical main roll carried on a shaft 41.which carries a bevel gear 42 which meshes with and is driven by a bevel gear 43, Fig. 17, which is carried on one end of a shaft 44, the other end of which is connected to and driven by an engine in any suitable manner. The

gears 42-43, as well as their vertical. and horizontal bearings, rest on a cast plate or platform, 45, which is again supported, by a cast plate 46. This cast plate is suspended from the top frame 1 by the side pieces 47, Fig. 24. In this manner the vertical shaft 41 and the horizontal shaft 44, with their gears and bearings are made part of the machine proper, thus maintaining a proper alinement and doing away with separate foundations. shaft 41 through the usual keys and pins but the shaft 41 is-hollow from end to end and through this hole is placed a rod 48 the upper end of which is fastened to a-bell shaped cup 49. The outer periphery of the I tire rests against and is rolled by roll 40, and while the drawing shows a plain roll this'roll might be furnished with a'groove so as to roll a flanged tire. The purpose of the cup 49 is to be forced down against the ripper edge of the tire, thus holding it in place and preventing it from lifting at this point, which action would be disastrous with a flangedtire. The lower-end of rod 48 is attached to a swiveled coupling 50 from the inside of which depends the cross piece 51. This cross piece is prevented from turning by guides in the cylinder casting 52'and it is connected by eye bars 53 to the piston 54. By admitting pressure water to cylinder ing through a fulcrumed and forked lever, 56, a plan of which is shown in Fig. 18, forces the swiveled coupling 50 upwards and releases the tire.

The verticalshaft 41. is at its top held in a bearing which is locatedin the main top frame 92. This bearing is made, up of separate pieces so asto allow for wear of journals, but it is also provided withtwo keys 57- 58, Figs. 17-25-27-28, the purpose of which is to conveni'ently adjust the shaft '41, in case of wear of the roll, so as to always maintain. the point z of the roll 40 in the same position, this being necessary to. main tain the: true circle.

Bearing against the inside of the tire, and close to roll 40, is the idler roll 59 which is revolving upon a vertical stationary shaft 60, Figs. 19, 20, 21. This shaft is firmly fixed in the sliding frame 61. To the opposite end of this frame are attached two bolts 62-63 which in turn are fastened to the cross head 64, Figs.

1 and 17, which is operatedby the cylinder 65 and its piston 66. When pressure of water is admitted to cylinder 65, this pressure is transmitted through the bolts 62-63 and sliding frame'61 to the vertical stationary shaft which again forces the idler 59 against the inside of the tire which in turn is backed up by the roll 40, thus reducing the blank in thickness ra-f dially while the roll 40 is being revolved. When the tire is finished and thewater is exhausted in cylinder the constant pressure cylinder 67, Figs. 1-17-19,

with its piston 68 pushes the roll 59 away from the roll 40 and leaves the tire clear for removal at this point.

The edging rolls 69-70, Figs. 1-2, are attached to asliding frame which is made of two pieces 71-72,

The vertical roll 40 is driven from the pushed down by the cylinder 74 through its piston 75. The shaft 73 is'surrounded by a vertically sliding bearing'76 which is operated by piston 75 through a sliding joint. The rear end of shaft 73 is pivoted on trunnions 77, permitting it to swing around same.

A pullback cylinder'78 acting through its piston 79 and tie rods 80, Figs..2-4-5, pulls the conical roll upwards and away from the tire the moment the water is exhausted from cylinder 74.

The loweredging roll 69 is keyed to the shaft 81, the lower end of which is driven from the horizontal main driving-shaft 44 through conical gears 82-83. The bearings 84 and 85 are provided with adjustable keys and screws 86 so as to take up wear of roll 69 for the purpose of maintaining the alinement of the mill,

the same purpose being accomplished with the top roll 70 by operating the screws 87, Fig. 3.

To the lower half frame 72, Fig. 2, is attached a hearing 88 which surrounds the projecting hub of the gear 82 to which is fastened an inside key 89, which again is driven by the main shaft 44. This shaft is provided with a key slot running through a considerable part of its length in order toenable the carriage frames 71-72, with their rolls and shafts, to move backwards and away from the rolls 40 and 59, while the tire isbeing rolled so as to suit its increasing diameter. This movement of the frame takes place in guides 90, Figs. 2-4-19-24,

the forward continuation of which furnish the guide slots for the sliding carriage 60 which carries the vertical idler pressure roll 59. v 1

91, Fig. 1, is an electric motor attached to the rame 92. Its pinion 93 meshes with the gear 94 on the long shaft 95. The two gears 96 on the ends of this shaft mesh with the gears 97 on the screw shafts 98, Figs. 1 and 6. To the upper sliding frame casting 7.1 are attached the two side arms 99, Figs. 14-6-8-9 and 10, which are securely bolted together. Slidingon the forward side of the side arms 99 are the two frames 100 containing the guide or centering rolls 101 which engage the outer periphery of the blank or tire. These rolls revolve on attached the gears 109 meshing with each other, thus insuring a motion to both if either one is driven. The bearings for these screws contain collars 110, Fig. 7 so as to take up end thrust. To one" of the screws is attached a spiral gear 111, which meshes with a spiral pinion 112, Figs. 6 and 7, which is attached to the side screws 98 by a sliding key 113. On each side of the,

sliding pinion 112 are the bearings 114, one or both of which contain nuts 115 that mesh with screw 98.

These-nuts are held in such a manner as to prevent their turning with the screw. It will be seen that if the side screws 98 are made one left and one right and Lin to move inwards or outwards while at the same time the frames .100 are simultaneously sliding inward or outward on the side arms 99. 1f when rolling the carriage 7172 is intended to slide backward and the frames 100 are simultaneously to slide outward. this can be accomplishedwith the mechanism shown and described with a proper selection of screws to be right or left and vice versa. I I

On the shaft 95 the gear 96 is not keyed but its hub runs through the bearing 116, see Fig- 37, and is bolted to a flange basting 118, which is rigidly keyed to shaft 95. This bolt connection is made so light that in case any undue strain should come to the screws above described these bolts will shear, thus forming a breaking point to act as a safety device in case of excess strain. 1. do not desire to confine myself to any particular safety device for this purpose; any suitable device can be used.

On the shaft 95 is the pinion 119 meshing into gear 120; on the shaft of this latter gear is the pinion 121 meshing into gear 1222, Figs. l-l7. The. shaft 123 for this latter gear continues outeach sideof it, one end being threaded right, the otherlcft. 'lwo cross heads 124, form nuts for the two screws above mentioned. The tops and bottom parts of the cross heads are trunnion shaped and are surrounded by square blocks 125, which are located in the bifurcated short ends of levers .120, Figs. 1, ll, 12, 14. These levers are fulcrunied on stationary pins 127 which are carried by the main frame 92. It will be seen that a turning of pinion 119 will cause a turning of levers 126 around their fulerums, the blocks 1'25 sliding out and in in the bifurcated outer end of the levers while atthe same, time following the trunnion shaped nut 124 out and in on the screw 123. The trunnion shaped nut is prevented from following the screw in its revolution by being guided on its one side by and against the guide block 1128, Figs. 1, 11 and 12, this guide block being bolted down. solidly to the fra1ne92. This guide furnishes also a means for taking up the great side thrust which is caused by the small angle be tween the screw and the bifurcated lever arm. If this angle was 90, that is, if the center line of lever and center line of screw were at right angles, there would be no side thrust. The opposite, or long or inner end of the lever 126 carries a guiding roll 12!). This roll is caried by the sliding frame 130 with blocks, keys and screws, as are the guide rolls 101. The frame 130 slides inand out on the guide piece 131, said guide piece being at its two ends fastened to and held by the main frame 92. It is now seen that the turning of pinion 119 will swing lever 126 on its fulcrum and push or ,pull the frame pieces 130 in or out on the guide 131 depending upon the direction of its rotation.

In adjusting the blrjlcks, keys and screws to take up wear on roll 129, it will be necessary to havea side ad just-merit in the top and bottom parts of the long end of lever 120. This adjustment is taken up by keys 1252, Figs. 1.1 and 13, or other convenient means for accomplishing the same end. (fear wheel 9 on shaft 95 is not directly connected to said shalt not eyed to a sleeve 133 Fi which Y assin throu *h the bearin s.

l O I O b 134-l35, is shaped so as to form part of a positive clutch, the other part 136 of which is keyed to shaft 95. The clutch as shown, or six llarly constructed. '1: ior

the purpose of enabling the driving of the side screws 98 to be discontinued, permitting the working of the guide rolls 129 only, but leaving the guide rolls 10] as well as the carriage 71- and 72 to remain at rest. This proceeding is at times necessary when running on special small rings when otherwise the conical rolls 69-40, if permitted to continue their inward movement, wouldiri'terfere with the sliding frame 61,

The gear 94 connects to pinion 119 by having the sleeve of this pinion pass through bearing 134, and by then being bolted to the flanged end of this sleeve through bolts 137 of such light dimensions that any unusual strain would break them. It is thus seen that any undue resistance in connection withthe screws, levers, &c., for operating the rolls 129 would merely shear the bolts 137. I do not confine myself to this safety device; any equivalent'may be used. In Fig. 33, a front view of the coupling 133136 is shown. Figs. 343536 show lever 141 for operating this coupling, but any other form of apparatus may be used. 7 V

In machinery'of this sort it is very important to be able to change the rolls rapidly. The guide rolls 129 101 are shown in the drawings as correct for a flat tire? if a flanged tire is to be manufactured the rolls as shown will have to he removed and grooved rolls inserted. The pins 102 and 138, Figs. 8*l0l3-l5, are pre vented from lifting and turning by a cap piece 139 which is fastened to the sliding frame 101l30 by two bolts 140. The middle part ofthis cap is slotted as shown in Fig. 10 and the upper ends of pins 102-138 are milled or planed to match this hole. It is thus seen that the pins 102l38 can neither rise nor turn when once set in a certain position. it will be furthermore seen that by removing the nut on the bolt 140 the cap 139 can belifted out of connection with the pins 102 138 after which these pins can he pulled up bodily and the rolls l01l29 taken out sidewise.

In solving the problem of the automatic action of the iour guide rolls so that they will all actto maintain a perfect circle with relation to point- 9:, Fig. 19, of the driven roll 40, not only a proper relation between the speeds of the necessary gears, screws, levers, rolls and motor must be observed but also there must he established and determined the proper angles A and B, Fig. 11, and the angle D, Fig. 6.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:-
